Description

An easy to grow annual, sunflowers have been cultivated in the United States for over 3000 years.  Indians increased the seed size approximately 1,000 percent by repeatedly selecting the largest seeds.

Plant foliage often depreciates as the summer progresses. Removal of browned and tattered plants from the garden after bloom may improve the appearance of the landscape, but is a great disappointment to local bird populations that love to feed on the seeds. If the plants must come down, consider saving the seed heads for feeding the birds in winter.

Sunflowers intermixed with other annuals provide good cover for many species of wildlife. Seeds are sought by many species of wild birds and small mammals like chipmunks and squirrels.  Muskrats and deer browse on the plants.

North American Indians grew sunflowers as both a food and medicinal plant with may uses.  Today, all parts of the sunflower plant are still used.  Sunflower seeds are widely available as food for both humans and animals.  Sunflower stalks have been used as fuel, fodder for livestock and food for poultry. The seed hulls are used for “litter” for poultry or returned to the soil or composted.  Today, hulls are used in the Soviet Union in manufacturing ethyl alcohol and furfural, in lining plywood, and in growing yeast. The stems have been used as a source of commercial fiber. The Chinese have used this fiber for the manufacturing of fabrics. Other countries are experimenting with the use of fiber in paper.  Additionally, yellow dye obtained from the flowers, and a black or dull blue dye from the seeds, were once important in Native American basketry and weaving.

Cultivars / Varieties

 Extensive crossing and hybridizing have resulted in a large number of cultivars that greatly expand the range of flower colors and flower head shapes . Dwarf varieties (1-3’ tall) and mammoth varieties (to 15’ tall) are also available.

While pollenless varieties are preferred for cut flowers, varieties with pollen are best for wildlife.
